"Thank you!!" Richards responded. "Thrilled to be part of this wild journey."

Richards will join Lisa Vanderpump, Kyle Richards, Lisa Rinna, Erika Girardi, Teddy Mellencamp Arroyave and Dorit Kemsley. Her involvement with the show was first rumored in June.

"Denise has been wanting to join the show for a long time," a source told People at the time. "She's a huge Housewives fan and watches all of the shows. And she has close relationships with many of the women in real life, including Kyle and Lisa Rinna."

"She's going to be a great fit. She's not afraid of the drama. And she lives a glamorous, Hollywood life -- which the show looks for," the insider added.

Richards is known for the films Starship Troopers, Wild Things and The World is Not Enough. She was married to Charlie Sheen from 2002 to 2006, and shares two daughters, Sam and Lola Rose, with the actor.
